Give the contemporary kit the gate it never had, and fix the five models it immediately caught: ninety coplanar faces across the kit, a waste and a tap hole built as open tubes that culled to black, and a barrier end that two readers in a row took for a fault.

/**
* The tap hole and the overflow, and neither is a real hole.
* The tap hole, the overflow and the waste, and NONE of them may be a
* tube with an open end.
*
* Cutting one would need the geometry the kit does not have. What it
* does have is that a hole is read as a DARK DISC BELOW THE SURFACE, so
* each is a shallow sunk cylinder in the shade of the glaze with its own
* floor. At any distance the model is looked at they are holes, and at
* the one distance they are not, they are recesses, which is what a
* basin's overflow actually is anyway.
* All three were built as short cylinders with `capTop: false`, on the
* reasoning that a hole is a shape you look into. It is not, in a
* renderer: an open tube shows you its own inside, its inside faces away
* from you, back-face culling removes it, and what is left is whatever
* was behind the basin. Looking down into the bowl the waste was a
* ragged black tear and the tap hole was nothing at all.
*
* What reads as a hole is a DARK SURFACE YOU CAN SEE -- a capped disc,
* sitting a hair proud so nothing can bury it, with a chamfer round it
* so its edge catches light the way a rolled rim does. Every one of the
* three is now that, and the only difference between them is which way
* they face.
